Comstock Armory Recessed Micro Brake (1/2-28, 5.56 bore) Plan-B Suppressor Mount

Comstock Armory Recessed Micro Brake 1/2-28 5.56 Plan-B Suppressor Mount

The Comstock Recessed 5.56 Micro Brake is a purpose-built component for shooters assembling a compact, repeatable Plan-B-pattern suppressor mounting system. It combines 17-4 PH stainless steel, a black nitride finish and clearly defined tool flats to support secure installation and convenient suppressor attachment. The product uses 1/2-28 threads and is compatible with common .900-24 Plan-B-pattern adapters, including recessed adapters such as the Comstock RPA.

Its brake geometry is designed to reduce recoil and to act as a sacrificial first surface ahead of the suppressor blast baffle. Because the body is rotationally symmetrical, it does not need to be timed with shims, simplifying installation and keeping the suppressor interface consistent.

Recoil Control and Blast-Baffle Protection

A Plan-B-compatible brake can improve control during unsuppressed fire while helping shield a suppressor's blast baffle during suppressed use. The compact design keeps added length manageable, and the stainless-steel body provides a durable mounting foundation for repeated attachment and removal. The recessed micro profile minimizes how far the device projects into the suppressor, which is especially useful when pairing a short blast chamber with a recessed adapter.

Fitment and Installation Guidance

Fits barrels up to 0.750 in diameter and is compatible with the SIG taper cap for taper-shoulder barrels; check other taper adapters for outside-diameter clearance. Before attaching any suppressor, verify bullet stability and confirm that the muzzle device, adapter and suppressor are concentric. Use an appropriate alignment rod and follow the current installation instructions supplied by Comstock Armory. Some suppressor manufacturers limit warranty coverage when aftermarket mounts or muzzle devices are used, so review the suppressor manufacturer's warranty and compatibility requirements before installation.
